WATER- FILTER.

ESPECIPICATION forrping part of Letters Patent No. 353,207, datedNovemesr'2 1386- 'scription of the same, reference being had to theaccompanying drawings and the letters of reference marked thereon,forming a part of this specification, in which Figure 1 represents avertical central section through the body of the device and lower partof the valve or faucet, the line a, Fig. 2, indicating the position ofthe section, as will be hereinafter more fully described. Fig. 2 i

represents a rear view of the device with-the attachinghead removed toshow the position of some of the internal parts and the generalconstruction. Fig. 3 represents a horizontal section, indicated by lineb b, Fig. 2, with the holding-head in place, as will be hereinafterdescribed. Fig. 4 represents a top or plan view of the faucet and faucetend of filter. Fig. 5 represents a portion of the section shown in Fig.3. Fig. 6 represents a similar horizontal section taken on line 0 0below the filteringbed, Fig. 1; and Fig. 7 represents atop or plan Viewof the filtering-beddetached, with portion of its filtering-coveringbroken away, and the rear end of the filtering-covering extended out, aswill be hereinafter more fully described.

To enable those skilled in the art to which my invention belongs to makeand use the same, I will proceed to describe it more in detail.

In the drawings, the part marked A is the bodyof the filter, and is madein circular form for convenience of finishing. The rear end, B, isprovided with a screwthread, d, to receive the screwthread e on theattaching part 0, whereby shoulder 8 of the attaching part can bescrewed up tight against shoulder 9 of rear part, B, of thefilter-cylinder A, and this part 0 is provided with a screw-stem, C, bywhich the filter is to be attached to the watersupply pipe, and whichattachment is usually accomplished by having a double screw-coupling,one end of which is screwed onto the water-pipe, and the other endscrews on the screw-stem G, which has a hole, 0 for the passage of thewater into the body of the filter. The hub part (3 of theattachingpart Ois made in the form of a nut, six-sided being preferred.

011 each side of the lower half of the body of the filter are cast orotherwise formed flanges f f, and between these flanges thefilteringgrate D is supported, the said grate being made of somesuitable metal, preferably non-corrosive, and is provided with a seriesof holes, 9, and over said grate is placed a wire-netting, D, and overthis netting is placed a filtering felt cloth, D, the rear end, D ofwhich is turned down over the rear end, E, of filterchainber E, andwhere said filter-cloth is held in place by holding-plate F, screws hpassing through said plate, filteringcloth, and into the head E, asfullyindicated in the drawings.

If preferred, fastening-plate F may be made to extend at its ends so asto fit the inner sides of the cylinder A, as indicated in dotted lines,Figs. 2 and 3.

The filtering-cloth D is turned over the side edges, k, of the grate D,so that when said grate and its wire-netting and filtering-cloth are runinto place, as shown in Figs. 1, 2, and 3, the desired and proper coveris produced for the chamber E, so that the water as it flows throughtheopening 0 must filter through the felting D in order to pass into thechamber E, from which it is to be drawn by means of the faucet G, whenits stein G is turned to bring the outlet-hole Z in line with hole at inthe front end, H, of filter-eylinder A.

The lower part of faucet-stem G is hollow, as shown at H, Figs. 1, 3, 5,and 6, and there is another outlet-hole, Z, in the stem G, which, whenon line with the hole m in head II, will draw water from above thefiltering felt cloth, and by this arrangement,when it is desired to drawfiltered water, stem G is turnedto bring its outlet-hole Z on line withholem, and which is done by turning faucet-handle I until pin 1 strikesagainst stop-pin 1 but, when it is desired to clean the upper surface offilteringcloth D handle I is turned in the opposite direction untilstop-pin I strikes against stoppin 1 when the water will rush over theupper surface of the filtercloth D ,out of hole at, and through thecorresponding hole, Z, in stem G into discharge-hole H, and out at thebottom nozzle,

It will be understood that the outlet-hole Z in stem G, which lets thewater into the stem from above the filtering-table, occupies the samerelation to its st0p-pin I as does the outlet-holeltoits stoppinl.Thesaidoutlet-hole, which works in connection with the upper hole, m, inhead H, is in the half of stem G that is cut away in Fig. 1.

The upper chamber, J, may be closed all but a narrow space, J, in whichcase the water as it is drawn off above the filter-cloth D" will perhapsclean off its upper surface in a more effectual manner.

In case the chamberJ is tobe closed a head, K, is provided with a bottomplate, K, and flanges a, cast on the sides of cylinder A and on theinside of head H, for supporting said division-plate K, and its headKwill be found good practical devices. One side of the opening Hinfaucctstem Gis of half circular form,

and the water as it passes out through openings or ports m m impingesagainst the flat sur face G, and as a result of such construction thewater issues from the nozzle H in a solid and compact stream, and not inflying spray or foam, as otherwise would be the case if hole H wereround or circular. Stem G in this instance is made tapering, and isground to fit a corresponding hole in the front projecting part, A, ofcylinder A.

The lower end, G of stem G is provided with a screw-thread, 0, toreceive the female screw-thread p of the nozzle end H The up per end ofnozzle H is grooved out, as shown at y, leaving a feather-edge, s, tocome in contact with the plane surfacet of the lower end of theprojection A. By this arrangement a good tightjoint is made, and that,too, in a manner not calculated to make the parts bind, while at thesame time packing devices are rendered unnecessary. If the featheredgewears off, by simply filing a little off of the lower screw end, G, ofstem G, nozzle H can be screwed up to make the edge 8 fit tight againstthe flat surface tof projection A. The projection to is made in the formof a nut, so that the nozzle H can be screwed on and off conveniently.The entire filter is simple in construction, and not liable to becomeclogged and to get out of order. The several parts can be easilyseparated when desired, and as easily put together again.

The action of the water as it passes through the filtering device downinto the chamber is such as to agitate the water in chamber E, therebykeeping it pure.

Having described my improved Water-filter, what I claim therein as newand of my invention, and desire to secure by Letters Patent,

1. The combination, with cylinder A, provided with attaching end 0, andheads E and H, the latter having ports or holes m m, of chambers E J,filtering-grate D, and filteringcloth D supported in the sides ofcylinder A, so as to bring the upper filtering surface thereof on a linewith port m, and two-way faucet G G, provided with a flatwater-impinging-surface, G upon its inside, as shown and described, saidparts being constructed and arranged in relation to each other as andfor the purposes set forth.

2. The combination, with cylinder A, provided with side fianges,ff, ofhead E, filteringgrate D, netting D, filtering-cloth D", and rearholding-plate, F, with its screws h h, substantially as and for thepurposes set forth.

3. The combination, with cylinder A and filteringeloth D supported on alevel with the bottom of port m, of head K and bottom plate, K,substantially as described, whereby a wide but thin water-space, J, isproduced, for the purposes stated.
